Triangle-shaped backrest cushion? Ivory/beige color. I received it as a gift, so I don't know the details. I cut off the tag because it was in the way. I've only had it in the corner of my room for a few months, and I mostly use other cushions, so it's practically unused. I think it's made of polyester. Width: Approximately 44cm, Height: Approximately 32cm, Bottom depth?: Approximately 17cm. I will compress it slightly for shipping. Can also be used as a body pillow. Recommended for those who like Nordic, natural, and linen styles.
